here is an image that is unmistakable theft.
the top image is Space Busters comic book #2 published by Ziff-Davis in 1951
the second image is a Turkish movie poster circa 1960s
the third image has all four issues of Space Busters & Space Patrol published by Ziff Davis (they are grouped as part of an ad for when I was publishing public domain comic books to digital).
I believe the comic at bottom right was also swiped for another poster by the Turks. if it wasn't that comic, then it was the one at top right. I have seen them both on ebay and Benito bought both copies of these posters, later posting them as 1930s or 1940s posters which is incorrect. I tried to find if Benito has them listed, but couldn't.
